Problem solved after nearly a week !😁😁
The Problem was that HypersHQ has to be set in the right way.
HyperHQ > WheelSettings > Choose Wheel ATARI 2600 > NavigationThemes > Check Clones use Parent vids ; Check Clones use Parent Themes;
Check Animate Out DefaultThemes (this i don´t know what it does?!), Check Reload Backgrounds
After checking these Boxes the Pictures of my Cardridges showed up everytime.
Anyhow Mates i hope although you could not help me, this will help others.
Happy playing to everyone !!!!
